Gas Molecule Assisted All‐Inorganic Dual‐Interface Passivation Strategy for High‐Performance Perovskite Solar Cells

The trap states at both the upper and bottom interfaces of perovskite layers significantly impact non-radiative carrier recombination. The widely used solvent-based passivation methods result in the disordered distribution of surface components, posing challenges for the commercial application of large-area perovskite solar cells (PSCs). To address this issue, a novel NH
